Etymology.
The specific name is a patronym in honour of
Vladimir
I. Ovtsharenko (
New York
,
USA
), a well known expert in
Gnaphosidae
who revised the genus.
Diagnosis
. The new species belongs to the
syntheticus
-group and most similar to
S. taukum
and
S. saidovi
sp. n.
It differs from
S. taukum
by partially fused hoods of the pocket (entirely fused in
S. taukum
), oval shaped and vertically directed copulatory openings (slanting, furrow (elongate oval) like copulatory openings in
S. taukum
) and median loops of copulatory ducts touching each other (spaced in
S. taukum
) (cf.
Figs 22‒24
and figs
43‒44 in
Ovtsharenko
et al.
[1994]
).
Synaphosus ovtsharenkoi
sp. n.
well differs from
S. saidovi
sp. n.
by pale colouration (cf.
Figs 1 and 5
) and copulatory openings located over pocket.
